Google’s original plans for Android included a subsidized, $9.99 unlimited monthly data plan to be offered by T-Mobile. The deal proposed in November 2006 obviously didn’t come to pass, but it was part of exhibits presented today in the trial for Oracle’s patent and lawsuit infringement claims against Google.

The unlimited data plan would include everything except photo updating, and be subsidized in part by Google forgoing a commission on each sale, according to CNET. Exhibits also showed an early prototype of the "Google Phone," which looked somewhat like a BlackBerry:

The Verge has more details and images illustrating the user interface Google was developing for Android in 2007. As you might expect, it looks a lot different from today’s Android interface.

The trial also brought out some Android revenue numbers—which could be important, as Oracle wants a percentage of Google revenue in damages. According to The Verge, a Google presentation from a July 2010 forecast predicted $278.1 million in Android revenue, primarily from ad sales. These figures are quite a bit out of date, though.

The trial is expected to last eight weeks. After the copyright phase is over, Oracle’s patent claims will be evaluated. According to ZDNet, closing arguments in the copyright phase are expected Monday, with a jury verdict potentially happening next week.

After the copyright issues are settled, Oracle will present its case that Google infringed at least two Java patents in Android. Oracle has asked for permission to assert a third patent that was invalidated—and then resurrected—by reviewers at the US Patent and Trademark Office, but a decision on that front has not yet been made.
